Strength Improvement

Studies were carried out to investigate the effect of hand grip strength and/or endurance improvement on blood flow through the muscles involved. One group of subjects trained for strength development and another for endurance development throughout a 29-week period. At regular intervals blood flow was measured under resting conditions and also following three different test exercise stresses designed to test the functional capacity of the vascular bed. Subjects who participated in the strength training program made significant gains in strength but not in endurance, while those subjects who trained for endurance improved in both strength and endurance. Resting blood flow was not changed significantly as a result of either training program. Significant changes in the blood flow response to the test exercise stresses were noted; these changes were associated with endurance rather than strength improvement. Submitted on April 3, 1961

The purpose of the study was the analysis of the growth dynamics of power indicators of athletes-bodybuilders at the stage of specialized basic training. Materials and methods. The study was conducted from March to the end of June (4 months) 2021. It involved 60 athletes aged from 18 to 19 years. Three research groups were formed, 20 athletes in each. These groups of athletes were divided by the usual sample method and by age. Qualification and anthropometric characteristics did not differ significantly. The only difference was in the proposed training programs. Theoretical analysis of scientific and methodological literature was carried out. Test control method for determining the maximum muscle strength of athletes to assess the initial level of muscle strength development in the surveyed contingent and determine the characteristics of its dynamics, was used. The obtained data were used to calculate the indicators of the value of the training load of athletes. In addition, method for quantitative assessment of athletes' physical load was used. The mathematical processing of research results was carried out using the software packages IBM SPSS Statistics 20. Results and discussion. The research results indicate that the values of the training loads indicators of bodybuilders and the nature of their changes in conditions of the same level of athletes' fitness and the structure of the training session depend on the characteristics of the selected training means (training programs). The analysis of the results obtained shows that under the conditions of the second variant of the training program, the indicators of the working mass of the athletes' equipment change more significantly during the entire research period. A similar tendency is observed when monitoring the load volume indicators, despite the fact that the most significant increase in this indicator among bodybuilders when performing formative exercises was obtained under the conditions of using the third variant of the training program, using the “premature fatigue” method. Conclusion. The growth rates of the strength capabilities of the main muscle groups turned out to be the highest among bodybuilders of the second main group due to the long-term use of the “premature fatigue” method. When performing exercises of a formative nature, the growth rate of strength capabilities was 30.9% (p <0.05), while when performing exercises of a basic nature, such an increase was three times less (by 10.5%, p <0.05)

Despite a relatively limited understanding of the factors associated with strength development, advances in equipment, and increased understanding of growth and maturation issues, have provided new insights into paediatric muscle strength development. Strength testing of children is performed routinely by researchers to monitor the determinants and development of strength throughout childhood, and also by physiotherapists to assess the degree of muscle disability and to diagnose the rate of recovery. It is important for strength test administrators to be equipped with knowledge of the normal age and sex-associated variations in strength and the factors attributable to that variation. Over time, the use of differing techniques to adjust for body size has changed our perspective of the historical concept of the age- and sex-associated differences in muscle strength. Likewise, the development of more sophisticated techniques to determine muscle size and body composition has allowed researchers to explore the factors associated with the development of strength during growth with a greater degree of validity.

This chapter focuses on laboratory-based strength assessment techniques and considerations for the paediatric population. The theoretical and practical considerations underlying strength assessment in adults and children and adolescents have been previously and thoroughly reviewed. This chapter will supplement, with emphasis on paediatric considerations, but not replicate, the material covered in these references. The topic of strength development and its correlates or determinants during childhood are beyond the scope of this chapter.

The study objective is to determine the influence of the combined method of strength development on the dynamics of training effect in girls aged 9 years. Materials and methods. The study involved 15 girls aged 9. The experiment was conducted according to the plan shown in Table 1. The study implemented the first variant of the combined method for developing arm and shoulder muscles (place I), abdominal muscle strength (place II), back muscle strength (place III), and leg muscle strength (place IV). The study materials were processed by the statistical analysis software – IBM SPSS 22. Discriminant analysis was performed. Results. The discriminant analysis indicates statistically significant changes in the training effect of strength exercises (places І–ІV, р < 0.001). The immediate and delayed training effect of strength exercises depends on the total amount of strength exercises in a physical education lesson. Thus, changes after training at each place of strength development are amplified by the subsequent exercises at other places, the differences between the testing indicators are statistically significant (p = 0.001). Conclusion. The study determined a positive training effect of strength exercises when using the combined method of strength development in the following modes: dynamic effort method – 3 repetitions, 30-s rest; maximum effort method – 1 repetition, 30-s rest; isometric effort method – 3 repetitions, 30-s rest; repeated effort method – 6 repetitions, 30-s rest. In strength load response, there are an immediate and delayed training effects. Thus it can be argued that it is possible to classify training effects by the presented battery of tests based on discriminant analysis.
